Stion, a solar photovoltaic company developing high-efficiency thin-film modules using proprietary materials and device structures, has hired Robert Wieting, who has 28 years of product development experience in photovoltaics, as vice president of research and development. In this position, Wieting will lead all of Stion's day-to-day R&D activities.
Wieting joins Stion from Regenesis Power LLC, a provider of turnkey photovoltaic systems financed using power purchase agreements, where he served as the company's chief technical officer. Prior to joining Regenesis, he was director of engineering at Shell Solar Industries, where he led the technical team from R&D to megawatt-scale manufacturing of the world's first fully qualified thin-film module made using copper indium diselenide (CIS). Wieting holds five U.S. patents focused on photovoltaics.
In addition, Stion has hired Steven Aragon, who has 20 years of experience in thin-film materials, processes and systems, as vice president of engineering. Aragon will lead Stion's efforts to scale up and optimize its product. He joins Stion from Daystar Technologies, a publicly traded manufacturer of thin-film photovoltaics, where he also worked as vice president of engineering.
Prior to joining Daystar, Aragon served as program manager for DC Plasma Power Products at Advanced Energy Industries, a $650 million company that provides power and flow technologies for thin-film manufacturing and solar power applications. While at Advanced Energy (AE), Aragon was responsible for design, development, and implementation of new product platforms that are now the flagship products in AE's thin-film solar line. He holds two U.S. patents.
